Aspartate aminotransferase, or AST (SGOT), is found in the liver, but also the brain, pancreas, heart, skeletal muscle, kidneys and lungs. Alanine aminotransferase, or ALT (SGPT), is primarily found in the liver. The normal range of values for AST (SGOT) is from 5 to 40 units per litre of serum (the liquid part of the blood). [The normal range of values for ALT (SGPT) is from 7 to 56 units per litre of serum.] The ranges of AST and ALT numbers may differ slightly depending on the technique and protocols used by different laboratories. However, normal reference ranges are routinely provided by each laboratory and printed in the report. The precise levels of these enzymes do not correlate well with the extent of liver damage or the prognosis (outlook). Thus, the exact levels of AST (SGOT) and ALT (SGPT) cannot be used to determine the degree of liver disease or to predict the future. It must be emphasized that higher than normal levels of these liver enzymes should not be automatically equated with liver disease. They may mean liver problems or they may not. Further tests are required to identify the cause. (As a polite word of correction, the opposite of 'normal' is abnormal - innormal as a word does not exist! No offence intended!)
ALL ANSWERS SHOULD BE THOROUGHLY RESEARCHED, IN ANY FORUM AND ESPECIALLY IN THIS ONE. - MANY ANSWERS ARE FLAWED.
